BEVERAGE- VENDING MACHINE.

To all whom it may concern Be it known that I, DANIEL J (Burmar' nnn, acitizen of the United States, residing at Los Angeles, in the county ofLos Angeles and State of California, have invented certain new anduseful Improvements in Beverage-Vending Machines, of which the followingis a specification, reference being drawings.

This invention relates to a beverage vending machine, and has for itsobject the construction of an efiicient and durable machine, which willdispense liquid, such as flavoring sirups, into a receptacle, such as acup, upon a person placing a coin in the machine and then operating themachine for discharging said liquid.

With this and other objects in view, my invention comprises certainnovel combinations, constructions and arrangements of parts as will behereinafter described, illustrated in the accompanying drawings, andmore particularly pointed out in the appended claims. a In the drawings:7

Figure 1 s a front View, in elevation, of a beverage vending machineconstructed in accordance-with the present invention.

Figure 2 is a top, plan view of a complete-vending machine, showing aportion of an adjoining, similar machine, as there may be any number ofthese machines associated together.

Figure 3 is a vertical, longitudinal, sectional view of the machine.

Figure 4 is a section, taken on line 4'-4, Fig. 2, andlooking in thedirection of the arrows.

Figure 5 is a sectional view, taken on line 5-5, Fig. 3, and looking inthe direction of the arrows.

Figure 6 is a section taken on line 66, Fig. 3, looking in the directionof the arrows.

Referring to the drawings by numerals, 1 designates the casing whichincludes the front section 2, the central section 3 and the rear section4. In the front section 2 is formed an upper coin slot 5, at the bottomof which is a compartment 6. that communicatm with a lower coin slot 7 5the had therein to the accompanying Specification 01' Letters Patent.Patented Feb, 28, 1922 Application filed November 2, 1920. Serial No.421,898.

lower coin slot 7 opens into the compart ment or receptacle 8.

Adjacent to the upper coin slot 5 is a' compartment 9, in which ismounted lever 10. Lever 10 is pivotally supported, at 11, wvithincompartment 9. Lever 10 has a coil spring 12 bearing against the samefor holding the lever out in the path of movement of a coin 13, Fig. 4.When the coin 13 is placed in slot 5, the weight of the coin issuflicient to overcome the outward pressure of the spring 12, resultingin the lever 10 being pushed inwardly as the coin travels to its lowestposition within the upper coin slot and into the compartment 6, Fig. 3.The lower end of lever 10 1s enlarged, at 14, and on one side of thisenlarged portion 14 are a pair of pins 15. A cog 16 is rotatably mountedin the compartment 9, and the' teeth of the cog engage the pins 15, ofthe lever 10; also, said teeth engage cups or receptacles 17 in thecompartment 18. One tooth of cog 16 only engages a cup 17, and when thelever 10 is pushed'inwardly by the coin 13, the tooth that is engaging acup will slightly raise the cup untilthe tooth passesthe edge of the cupand then the cup will dropdown and out of the compartment 18 and thenext cup will fall against a tooth of the cog and will not be dischargeduntil another coin has been dropped into the slot 5. The lower pin onthe lever 10 operates'or rotates the cog, while the upper pin acts as astop or brake for limiting rotary movement of the cog each time the coin13 is dropped in the slot 5.

A primary valve 19 is positioned in the central sect10n'3 of the casing1, and an auxiliary valve 20 is positioned in the rear section 4. Theprimary valve 19 is operated by a coin-controlled pusher device," thiscoin-controlled pusher device comprises a manually-controlledoutersection 21 and an inner section 22 (Fig. 3). The outer section 21includes the push cap 23, pin 24 and spring 25; The inner end of the pin24 is adapted to bear against the coin 13, when in the compartment 6 atthe lower end of the upper slot 5, and upon the push cap 23 beingpressed inwardly by the operator, the cap 26 of the inner section 22will be pushed inwardly; the shaft or pin 27 is attached at one end ofthe cap 26 and itsother end is attached to the prlmary valve 19. Aspring 28' is mounted upon pin '27 for normally holding the valve 19 ina closed position upon its valve seat 29, and said spring 28 alsoretains the outer end of the cap 26 in position to be engaged by a com13 when one is dropped into the compartment 6. If no coin is inthecompartment 6, and. the push cap 23 is pressed inwardly, the innerend of pin 24 will ride into the socket 30, which socket extendslaconsiderable d stance into pin 27, as shown by dotted lines, Fig. 3.

The auxiliary valve .20 is operated by liquid pressure; a shaft or in 31is fastened to valve 20, and" on t e inner end of pin 31 is a plungerhead or cap 32 against which the liquid engages, and when pressure issufficient the ca 32 w ll be forced toward the outer en of cas1ng 1,moving the valve 20 outwardly from its seat, permitting water orcarbonated water to enter the rear end 33 of the casing 1, passing fromthe section 4 into by-pass pipe 34 and discharged into the nozzle 35.

A sirup receptacle 36, preferably formed of transparent material, suchas glass, is mounted upon the casing 1 and communicates with theinterior thereof (Fi 3). A valved device 37 is mounted upon t ereceptacle 36 for permitting air to pass from within the receptacle assirup or liquid fills the same. Sirup is supplied to the receptacle 1 bysupply pipe 38.

It is-to be understood that spring 28, as well as spring 38 normallyretain the valves 19 and 20, respectively. in a closed or seatedposition for preventing liquid to pass through the casing until a coinhas been dropped into the machine, whereupon the manually-operatedpusher device can be forced inward to move the primary valve 19 to anopen position, permitting the liquid or sirup in the receptacle 36 to bedischarged by the valve 19 and through the nozzle 35 into a cup or recetacle placed below the nozzle, as shown in ig. 5. The supply pipe 38normally keeps the receptacle 36 filled. The inward movement of thevalve 19, from its seated position, will result in it pushing againstthe plunger head or cap 32 forcing it inwardly, causing the auxiliaryvalve 20 to move to an open position, permitting water or carbonatedwater to pass by the auxiliary valve into pipe 34-. and be discharged atthe same time the sirup is discharged, through the nozzle 35, into thecup 17. On the extreme inner end of the shaft or pin 27, is a closuredevice 39 that closes the inner end of the supply pipe 38, (see dottedlines, Fig. 3) opening into the section 3, when the primary valve 19 hasmoved to its innermost position, thereby preventing momentarily any moresirup from entering the casing 1 or the receptacle 36, until the 55liquid in receptacle 36 has been discharged and the primary valve 19 hasmoved to its seated position, F'i 3.

If it is desired, the auxiliary valve device, constituted by the valve20 pin 31 and cap 32, may be entirely remove and by closing valve 40, ofthe supply pipe 38, a mixed beverage suppl pipe may be attached, at 33,an upon t e primary valve device being actuated, to move the valve 19 toan open position, the mixed beverage will pass from the inner end of thecasing 1, through the nozzle 35 into receptacle or cup 17.

It is to be understood that a number of my machinesmay be associatedtogether, as indicated in Fig.2; ata soda fountain, these machines may''be arranged in series, with a common water or carbonated water supplypipe connected to all of the casing, at 33. A different sirup isdischarged into each receptacle 36, through supply pipe 38.

Of course, it will be understood that when valve 40 is closed, valve 40on pipe 34 will have to be closed too, so that the mixed liquids beingsupplied at 33 will have to pass directly through the casing to thenozzle 35. Ordinarily both valves 40 and 40 will be left open so as toallow free passage of liquid during the Operation of the machine,including the primary and auxiliary valve devices shown clearly in Fi 3.

While I have described the pre erred embodiment of my invention, andhave illustrated the sa'me'in the accompanying drawings, certain minorchanges or alterations may appear to one skilled in the art to whichthis invention relates, during the extensive manufacture of the same andI, therefore, reserve the right to make such alterations or changes asshall fairly fall within the scope of the appended claims.

What I claim is:

1. In a machine of the class described, the combination of a casingprovided with a nozzle, a manually-operated coin-controlled valve devicein said-casing, a liquid-operated auxiliary valve device in said casing,means formed upon the casing for permitting liquid to pass by said valvedevices and be discharged through the nozzle when the valve devices areoperated, and a container mounted upon said casing and adapted to beemptied when the valve devices are operated,
